Just be careful of how long the material will last. While the shrink wrap has some UV protection, it's not rated fer the wind loads and temps over time that you will be subjecting it to on the road. You will need to inspect it carefully each time you go out and know that as you approach the 6 month mark, it may need to be replaced. I have some reservations of the material lasting more than a year.

With any luck by 1 year in I will he happy with my shapes and can spend $76.95usd Approximately 1 yd² / linear meter for the material in post#6 $76.95 USD ORATEX 6000 . ORATEX 600 @$54.95 Approximately 1 yd² / linear meter +shiping from Germany. as well as a small list of consumables.

i'm surprised it weighs 150lbs. is the frame steel rod?
i like your idea and will keep this in mind. i imagine i could make a frame and use that material to make a kammback. lightweight and easy to use. plus my car is white.
when it's heated, will it only stick to itself or would it also stick to a painted surface?

The final product will be able to be raised and locked up as a wing for towing an enclosed trailer (as most Comercial units camper or box have a flat front ) ever tow a box trailer with a VW Bug not easy

While in Las Vegas NV temps were geting over110°f and the plastic relaxed Slightly about 1/4" so I used some "light"tan hammer tone plastic compatible rattle can paint. Painted over the wight duct tape burn hole patches. Figured it would help as sunscreen spf 100. Maby. However much ro my dismay it turned out a dark copper. So during my 2nd trip to LV the heat sag was much larger problem @ about 117°f it would sag about .5" on the 2 center spans at the hottest part of the day. But the plastics would go back to tight after about 1-5min of driving got back to the soggy cool NWand it was back to a snear drum.

BamZipPow you called it 6months. However the Oratex has been tested past 10years passing FAA testing so it will work for the long hual. Srick and shrink repairable easy compound curves
Hear is a hammer test with the Oratex I found. http://https://youtu.be/yoI5PEIxtEg

Well 6 months in I saw 3/4" crack form in week spots only(over heated cussing it to thin after thickening)

tube from a 4 in. fat tire bike as a gap filler
May up to pool noodles I didnt account for rhe forward lean of the back of the cab v2.0 will.
The last 2 are learning curve errors
paint chiped off from improper attachment
The missing paint(bright spots) was caused by the bace plastic changing to much strechmarks given time theas would become cracks justified an extra 10# of steal fraim work
wasn't melted well enough and separated nextto hot
Changes for v1.2
Added 1/2" Millar backed fome between the fraim and plastic. It softened the allmity side to top transition and noise suppression
Added an inner hoop for mounting point.
Added lift struts.
Added a latch mechanism
Added Garage goor seal for bededge seal

these were taken after 2mi at 25 mph and 1mi at 45mph out side Anaconda, MT
notice the vortex patterns at the transition from horizontal to vertical
I only cleared the snow from the windshield, side windows and hood

these were taken near Wisdom, MT 10mi at 60mph
the first one shows the air attachment going to the tail in the horizontal plain and warping in in the back from vertical

a small disturbance behind the hinge other wise it looks like the "ladder rack" [part that protrudes above the cab ] dues not create much disturbance , as expected some but small. the air is steal able to stay attached
these were taken at Georgetown lake speeds of up to 70mph
this shows the termination past the tailgate after I built the canape I noticed that "ALL" the new trucked have a similar shape added to the top of the tailgate depending on the make from 2"-6" to help brake the vacuum bubble at the tailgate

and to show why a 2 piece canape. It's a truck its gotto be able to work. 30 70lbs bails of hay
so far I'm avraging 24mpgs on the flats with a 22mpg low and 27.9mpg all time high
